IPC: H01M4/14
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a battery having excellent life performance, by making a grid by expanding or blanking a sheet made of a lead alloy and filling the grid with a paste-like active material including lead powder obtained by utilizing blanked wastes then produced. SOLUTION: A blanked grid is formed by blanking a rolled sheet made out of a slab of a tin alloy having 0.07 wt.% lead and 1.5 wt.% calcium. A fixed amount of blanked waste produced by the blanking is put into, and pulverized by, a ball mill pulverizer, thereby making lead powder, and the lead powder thus obtained out of the blanked waste of various kinds is mixed at various mixing ratios with lead powder obtained out of a pure lead block and kneaded with dilute sulfuric acid, thereby making a paste-like active material, which is packed in the grid to make a positive electrode plate. By using the blanking waste for filling the grid, a cost increase due to the blanked waste is substantially thoroughly eliminated, and the amount of lead blocks case for making lead powder is decreased, whereby reducing costs.

Title: Alignment device
Inventor: KAMONO TAKASHI
IPC: G01B11/00
Filed: 1986-07-25
Abstract: PURPOSE:To perform high-accuracy alignment when the alignment is performed by using light reflected by a reflection mirror by correcting an error in return position generated when the reflection mirror is returned after a wafer surface is shot by using the signal of a detecting means. CONSTITUTION:When the reflection mirror 13 is at its normal position as shown by a solid line, two alignment light beams of different wavelength forming images at a point P2 on the surface of the wafer 4 form images on points P1 and P2 on straight lines P1 and P0. Then, when the mirror 13 shifts from the normal position by an angle theta/2 and returns, one of two light beams of different wavelength forming an image at a point P'0 on the surface of the wafer 4 forms an image at a point P'1 on the surface of a reticle 1 and the other light beam forms an image at a point P'0. The difference in length between those segments P1P'1 and P0P'0 causes variation in offset value between the two light beams. For the purpose, the reflection position D' of, for example, luminous flux from a light source 14 based on the mirror 13 is detected 15 and the output of the detecting means 15 is utilized to adjust the offset between the two wavelengths. Consequently, the position error of the mirror 13 is corrected to prevent alignment accuracy from deteriorating owing to chromatic aberration at the time of use of plural wavelengths.
